Astrophysics Seminar: Mapping Cosmic Star Formation with the CO Mapping Array Project
Patrick Breysse (NYU)
I will discuss the results of the second observing season of the CO Mapping Array Project (COMAP). COMAP is a line intensity mapping experiment seeking to probe the cosmic star formation history by mapping the 115…
Condensed and Living Matter Seminar: Van der Waals magnets and antiferromagnets interacting with electron spins
Dan Ralph (Cornell University)
This talk will discuss two projects. The first concerns topological insulator/magnet samples made by mechanical stacking of exfoliated van der Waals flakes. The proximity interaction of the…
High Energy Theory Seminar: Apparent Fine Tunings for Field Theories with Broken Space-Time Symmetries
Alberto Nicolis (Columbia University)
I will exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These theories possess bounded target…
Profs & Pints Philadelphia: Finding the Cosmic Puzzle's Missing Pieces
Mark Trodden (UPenn)
Profs and Pints Philadelphia presents: “Finding the Cosmic Puzzle’s Missing Pieces,” a look at how the fields of astronomy and subatomic physics are working in tandem to shed light on the darkest parts of the…
Astrophysics Seminar: Exploring solutions to the galaxy diversity problem
Akaxia Cruz (Flatiron Institute/Princeton University)
On large scales the Universe is well described by a cosmological model where matter primarily comprises cold dark matter (CDM), a single collision-less particle species with negligible primordial thermal dispersion.…
Condensed and Living Matter Seminar: "Robots that evolve on demand"
Rebecca Kramer-Bottiglio (Yale)
Abstract: Soft robots have the potential to adapt their morphology and behavioral control policy to changing tasks and environments. Inspired by the dynamic plasticity of living materials and general adaptability of…
High Energy Theory Seminar: Causality constraints on EFTs
Sera Cremonini (Leigh University)
I will discuss how causality can be used to place bounds on higher derivative corrections to Einstein Maxwell theory. Scattering probe photons off of charged shock waves, we obtain new constraints on the Wilson…
Colloquium: The Wide-angle View of Dark Matter in Nearby Galaxies
Robyn Sanderson (University of Pennsylvania)
The Gaia astrometric survey has delivered a detailed “close-up” of our Galaxy, the Milky Way, by measuring precise 3D positions and…
High Energy Theory Seminar: "TBA"
Brian McPeak (McGill University)
Astrophysics Seminar: Examining the CMB quadrupole anomaly using Planck PR3 data
Jahmour Givans (Princeton University)
Observations of the large-angular-scale autocorrelation function and power spectrum of the cosmic microwave background (CMB) over the last 30 years have consistently provided hints that our standard LCDM cosmological…
